      FAQs

      Questions customers ask us

      All FAQs
      Why go solar?

      Solar cuts your electricity bill from the very first month, shields you from every tariff hike and is good for the environment. Homes also get the PM Surya Ghar subsidy.

      How much does a system cost?

      Cost depends on size, roof and components. Homes typically need 3-10 kW. Use our savings calculator for an estimate, and we confirm the price after a free site visit.

      How long do solar panels last?

      Good panels last 25 years or more and usually carry a 25-year performance warranty.

      Is maintenance required?

      Very little: regular cleaning and a health check once a year. Take our AMC plan and we look after it for you.

      Do panels work at night or on cloudy days?

      Panels produce less on cloudy days and nothing at night. On-grid systems draw from the grid when needed; add a battery if you want backup.

      How long does installation take?

      A home system is usually installed in 1 to 3 days. Approvals and the net meter depend on your DISCOM; we track them for you.

      Will solar work during a power cut?

      A normal on-grid system switches off when the grid fails, for safety. For backup, choose a hybrid system with a battery; see solar + battery storage.

      Do you install solar water pumps for farms?

      Yes. We size the panels and pump controller to your borewell depth and pump, and install them as a ground-mounted system. Ask for a free site visit.

      Every GreenCube system is installed by technicians trained at our group institute, GreenPower Training and Research Institute.
